DURAN® Erlenmeyer Flask (Conical Flask)
Your Location: Main>Consumables>Glassware>DURAN® Erlenmeyer Flask (Conical Flask)
Typical uses for DURAN Erlenmeyer flasks include boiliing and swirling. They are also used as components in apparatus. Their shape makes them ideal for mixing and storing liquids.
An advantage of the conical shape is that there is little tendency for precipitates to stick to the inside surface as they slide down the wall with the rest of the contents. DURAN Erlenmeyer flasks are also used as culture flasks.
DURAN® Erlenmeyer Flask
narrow neck
With easy-to-read scale and large labelling field for easy marking in fired-on, highly durable, white ceramic. Due to conical form, suited to the mixing of liquids. Uniform wall thickness distribution makes these flasks ideal for heating applications.

DURAN® SUPER DUTY Erlenmeyer Flask
narrow neck, with reinforced rim
The DURAN® SUPER DUTY products are characterized by a higher mechanical strength achieved by reinforcing the rim. As a result of this modification, the impact strength is improved, and the risk of accidental breakage is significantly reduced.
Application note: To avoid breakages due to thermal stress, uniform and slow heating of SUPER DUTY products is recommended.
